Solvent Extraction of Cd(II) using n-Butylamine-ClO:-MIBK
and n-Butylamine-Oxine-MIBK

Abstract

n-Butylamine-perchlorate-1WJBK and n-butylamine-oxine-MIBK extractants were found to be effective for the extraction
of Cd(II) ions under strongly alkaline conditions (pH>10). This extraction is a function of the concentration of
oxine, perchlorate, n-butylamine and pH. The flame AAS signal for Cd(II) was considerably enhanced by using the
above extractants. The signal enhancement and the increase in % extraction of Cd(II) can be attributed to the
formation of synergistic amine adducts.
